Bottle-neck.



JAMES BENTLEY, OF WISE, VIRGINIA.

BOTTLE-NECK.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed July 12, 1917. Serial No. 180,199.

To all whom it may concern Be it known that I, JAMES W. BENTLEY, a citizen of the United States, residing at Wise, in the county of Wise and State of Virginia, have invented certain new and useful Improvements in Bottle-Necks, of

' vide a device of this character, which is simple and durable in construction, reliable and efficient in operation and one which can be manufactured'and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a longitudinal section through the neck of the bottle with my invent-ion in place.

Fig. 2 is a section on line 22 of Fig.1.

Fig. 3 is a section on line 3-3 of Fig. 1.

In these figures, 1 represents the bottle neck having a reduced part 2 where it joins the body to form a seat for the stopper 3. Substantially midway of the ends of the neck a groove 4 is provided of annular shape which is adapted to receive the split ring 5 which holds the cylindrical casing 6 in the bottle neck. An annular groove 7 is formed on the outer surface of said casing by pressing the metalthereof inwardly as shown in Fig. 1. A shoulder 8 is also formed on the inner face of the casing 6 by this operation of forming the groove. The split ring 5 is of sufficient width to engage both the groove 4 in the bottle and the groove 7 in the casing to hold said casing in place against longitudinal movement. The stopper 8 is made substantially conical or acorn shaped with its pointed end extending downwardly through the reduced opening 2 and has a Wedge action in said opening so that a tight fit is secured between the stopper and opening. The upper or outer end of the stopper is in skeleton form comprising small rods 9 projecting upwardly from the solid body of the stopper and an annular plate 10 is supported by said rods. This plate has a central opening 11 therein and said plate is made of greater diameter than the pressed in part of the casing so as to engage the shoulder 8 when the bottle is turned over and thus the plate is prevented from leaving the neck of the bottle. Said plate acts as a bafile plate for preventing the insertion of tools or the like into the neck for engaging with the rods on the stopper to raise the stopper and thus permit the bottle to be refilled.

l/Vhen the bottle is filled the stopper 3 is placed in position, and the plate 10 is then placed on the ends of the rods 9 and then the casing with the split ring compressed within the groove 7 is forced down into the neck until the ring reaches the groove 4 in the neck when it will spring into the same and thus lock the casing within the neck. lVhen the contents of the bottle are to be used, the bottle is tilted so that the plate and stopper will slide forward to uncover the opening 2 and thus the liquid will flow past the stopper through the opening 11 in the ring or plate and out of the mouth of the bottle. As soon as the bottle is placed in upright position again the parts will assume their original position and thus close the bottle so that it is impossible to refill the bottle. As before stated the plate 10 will prevent the insertion of a tool to grasp the stopper to lift the same.

I prefer to make the stopper of some light material such as cork, so that if an attempt should be made to refill the bottle by turning the same upsidedown the liquid would cause said stopper to close the opening. The cork stopper should have a metal cap to prevent puncturing.

It is thought from the foregoing that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make slight changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

I claim as my invention: A bottle neck having an annular groove on itsinner face a lining to fit snugly in position, a split ring for insertion in both of said grooves to lockthe casing against Withdrawal, and a stopper to be positioned inside said "shoulder and carrying a plate forengagement With the shoulder to limit the outward movement of the stopper. 7

In testimony whereof I aflix my signature in presence of tWo Witnesses.

JAMES W. BENTLEY.
